I have found two seperate issues that confound me with the latest version of ImgBurn (2.5.8.0):
1.) Attempting to burn a very small ISO (Kon-Boot) fails every time; until you manually choose to burn with TAO instead of with SAO.
I stumbled across this information while searching for a solution and after changing to TAO the 'Test' completed successfully.
(I do not recall where I found this tip, but it was responded to by the developer stating that they would implement something to automatically change the SAO setting to TAO for burning very small images. 2009?)
2.) While preparing to post the ImgBurn log I found that it did not exist even though I had preferences set to create and append the existing log. I changed the location for the logs to a higher level and tried again.
Selecting 'Append Existing' will write the log one time only. Sequential operations do not change the log from its original state.
Selecting 'Overwrite Existing' actually appends the log. The following log was written with 'Overwrite' enabled.
